Formal wear.
Address is: 43800 Olympic Blvd. Leesburg, VA 20176 When you turn in, you'll reach a gate. Tell them you are there for a wedding at the Rivercreek. Go all the way down, drive slow and fully stop at the stop signs. You'll approach the end of the road, park on the right side and enter through the front.
If I say yes, no one will show up so, you'll just have to find out. Bring small bills for bar tips.
